Strana 63 - Style four sided, tapering ; stigma minute, pubescent ; germ roundish, concealed within the spadix. After the spathe decays, the spadix continues to grow, and with it every part of the flowers except the anthers. When the fruit is ripe, the spadix has attained many times its original dimensions, while the calyx, filaments and style are larger, very prominent and separated from each other. Within the spadix at the base of each style is a round, fleshy seed, as large as a pea, white...
Strana 182 - are ten depressions or pits, accompanied with corresponding prominences on the outside. In these depressions the anthers are found lodged at the time when the flower expands. The stamens grow from the base of the corolla, and bend outwardly, so as to lodge the anthers in the cells of the corolla. From this confinement they liberate themselves, during the period of flowering, and strike against the sides of the stigma.
Strana 107 - Sot. nag. t. 280. Bigelow med. hot. ii. t. 36. — Sides of fences and borders of woods in the United States. (Dog's bane.) Height from 3 to 6 feet. Stalk smooth, simple below, branching repeatedly at top, red on the side exposed to the sun. Leaves opposite, smooth on both sides, paler beneath, ovate, acute, on short petioles. The flowers grow in nodding cymes from the ends of the branches and axils of the upper leaves, furnished with minute, acute bractes. Calyx 5-cleft, acute, much shorter than...
Strana 109 - The pollen forms ten distinct, yellowish, transparent bodies, of a flat and spatulate form, ending in curved filaments, which unite them by pairs to a minute dark tubercle at top. Each pair is suspended in the cells of two adjoining anthers, so that if a needle be inserted between the membranous edges of two anthers and forced out at top, it carries with it a pair of the pollen masses. Pistils two, completely concealed within the mass of anthers. Germs ovate, with erect styles. The fruit, as in other...
Strana 323 - Bigelow was surely a genius. Working in a period when it was sacrilege to doubt the immutability of species, he wrote in 1824, in the 2nd edition of Florula Bostoniensis, concerning the goldenrods and asters (Solidago and Aster) : "Among the species there are a vast variety of hybrids and subspecies which the labors of botanists have not yet been able to reduce under permanent characters, though names without number have been applied to fugitive varieties. The single species found in Great Britain...
Strana 442 - The leafets or divisions of a pinnate leaf. Pinnate. A leaf is pinnate when the leafets are arranged in two rows on the side of a common petiole; as in the Ash, Elder, and Rose.
